"The Chief Minister will go along with Prime Minister Narendra Modi to Bangladesh next month. We hope this visit will strengthen relations between the two Bengals (West Bengal and Bangladesh) and also between the two countries," state's Education and Parliamentary Affairs Minister Partha Chatterjee said.

There was speculation in the media about whether the Chief Minister will accompany Modi on his first trip to Bangladesh after taking office.

Teesta water sharing issue is likely to come up for discussion during the visit. The Teesta deal was set to be inked during the then Prime Minister Manmohan Singh's visit to Bangladesh in September 2011 but was postponed at the last minute due to objections by Mamata.

Union Home Minister Rajnath Singh said in Kolkata that India and Bangladesh would soon approve the long-pending Teesta river water-sharing agreement.

"Both the countries will give their approval to it very soon. We are hopeful that we will get full cooperation from West Bengal government", Singh said.

Last week, Bangladesh had hoped that the pact will be inked during Modi's trip.

The Teesta water is crucial for Bangladesh, especially in the leanest period from December to March when the water flow often temporarily comes down to less than 1,000 cusecs from 5,000 cusecs every year.
